2025-04-23platform: generic: Remove platform override hooksSamuel Holland1-1/+1
Now that all of the overrides are modifying generic_platform_ops directly, remove the unused hooks and forwarding functions. The remaining members of struct platform_override match struct fdt_driver, so use that type instead. This allows a future commit to reuse the fdt_driver-based init function.

2025-04-23platform: generic: Modify platform ops instead of using hooksSamuel Holland1-8/+9
Switch all existing platform overrides to use the helper pattern instead of the platform hooks. After this commit, only the .match_table and .init members of struct platform_override are used. There are two minor behavioral differences: - For Allwinner D1, fdt_add_cpu_idle_states() is now called before the body of generic_final_init(). This should have no functional impact. - For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is missing, the code now falls back to using generic_coldboot_harts, instead of accepting any hart.

2025-04-23platform: generic: Add an init hook matching fdt_driverSamuel Holland1-2/+5
In preparation for reusing the fdt_driver code to match platform overrides, add a new .init hook matching the type signature from fdt_driver. This hook replaces the existing .fw_init hook, since it is called at roughly the same place in the init process.

2025-02-12lib: utils: Initialize miscellaneous drivers in one passSamuel Holland1-1/+1
For driver subsystems that are not tightly integrated into the OpenSBI init sequence, it is not important that the drivers are initialized in any particular order. By putting all of these drivers in one array, they can all be initialized with a single pass through the devicetree. This saves about 10 ms of boot time on HiFive Unmatched.

2024-11-28lib: utils/reset: Use fdt_driver for initializationSamuel Holland1-2/+7
The reset driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. The generic fdt_reset_init() performs a best-effort initialization of all matching DT nodes. Platform-specific logic expects exactly one DT node to match a single driver. This is accomplished by using fdt_driver_init_one() with a local list containing that one driver.

2024-08-24platform: generic: Pass FDT to early/final_init overridesSamuel Holland1-3/+1
Several of these override functions access the FDT blob. Explicitly indicate which callbacks are allowed to modify the FDT blob by passing the parameter as a possibly-const pointer. This also reduces code size by deduplicating the call to fdt_get_address().

2024-02-22platform: starfive: call starfive_jh7110_inst_init() in pm_reset_init()Nam Cao1-1/+6
The function starfive_jh7110_inst_init() initialize some power management unit address and clock addresses, needed for the reset driver. It doesn't do anything else, and also the reset driver doesn't work without calling this function. Thus, it does not make much sense that this function is independent from pm_reset_init(). Delete the separate call to starfive_jh7110_inst_init(), and instead just call this function inside pm_reset_init(). Doing this also fixes another problem: if starfive_jh7110_inst_init() returns an error code, it gets propagated to final_init() and OpenSBI hangs. This hang is not necessary, because failures within starfive_jh7110_inst_init() only mean OpenSBI cannot perform reboot or shutdown, but the system can still function normally.

2024-02-22platform: starfive: return error if needed devices are not presentNam Cao1-0/+4
Jh7110's reset driver needs power management device and clock controller device to work. Currently, the driver proceed anyway without these devices, and invalid addresses (jh7110_inst.pmu_reg_base and jh7110_inst.clk_reg_base) are used during reboot, which causes unpredictable broken behaviors. If these devices are not present, return -SBI_ENODEV. Signed-off-by: Nam Cao <namcao@linutronix.de> Tested-by: Minda Chen <minda.chen@starfivetech.com> Reviewed-by: Anup Patel <anup@brainfault.org>
2024-02-22platform: starfive: rename "stf,axp15060-regulator" -> "x-powers,axp15060"Nam Cao1-1/+1
OpenSBI uses the device tree compatible string "stf,axp15060-regulator" for the regulator node. However, the string used by U-Boot (and Linux) is actually "x-powers,axp15060". As OpenSBI gets the device tree from U-Boot, this causes the regulator device to be undetected, and OpenSBI does not use this device to perform board reset/shutdown. Rename this device tree compatible string to match U-Boot (and Linux).

2024-02-22platform: starfive: get I2C offset address from clocks propertyNam Cao1-10/+14
The current code gets the I2C offset address using the device tree node name: it get the I2C device index from the 4th character in the node name (for example, "i2c5" -> i2c device 5). However, the device tree node's name in U-Boot is actually just "i2c" without the number, so the current code cannot be used with the device tree from U-Boot. Get the I2C offset address from the "clocks" property instead.

2024-02-22platform: starfive: correct system clock device tree nodeNam Cao1-1/+1
Starfive names the system clock device tree node "starfive,jh7110-clkgen" in all their git repositories. However, a different name is used in upstream U-Boot (and also Linux): "starfive,jh7110-syscrg". Since OpenSBI gets the device tree from U-Boot, this inconsistency leads the problem that OpenSBI doesn't know the system clock device exists. Correct this name to keep the consistency.
